Aircon Cycle and How Aircon Works

Aircon is a piece of amazing equipment which was invented many years back to keep you cool. Its origin can be traced back to ancient Egypt. Its full name is air conditioner and its abbreviation is AC. The first modern electrical aircon was invented by Willis Carrier in 1902.

Aircon and Refrigerant Cycle (How Aircon Works)?

To explain how aircon works, you need to understand the aircon cycle. In an aircon cycle, there are 3 main concepts:

When liquid evaporates to form gas, heat is absorbed. This creates cooling effect.

When gas condenses to liquid, heat is given off. This creates the heating effect.

Temperature of boiling point increases when pressure increases. The same decreases when pressure decreases. Boiling point is the temperature when liquid evaporates or gas condenses.

Aircon needs a gas called refrigerant with lower boiling point so that it evaporates and condenses more easily and especially when pressure is altered. The refrigerant goes round and round to cool the room and is assisted by four components – a compressor, a condenser, an expansion valve and an evaporator – in cooling the air.

When the aircon technician pumps gas into your aircon, he is effectively pumping refrigerant into your aircon. The refrigerant in vapour stage is then subjected to high pressure at the compressor. This brings up the temperature of boiling point of the vapour such that it can be condensed easily by blowing normal air on the tubes containing it. In the process of condensation, gas refrigerant changes to liquid refrigerant and heat is released. This process takes place at the compressor-condenser unit.

The liquid refrigerant then passes through an expansion valve where the pressure is reduced. This brings the temperature of boiling point down. This means that the low-pressure liquid refrigerant can easily be evaporated by blowing normal air around us on it. The low-pressure liquid refrigerant then travels to the evaporator where the fan blows the air on it. When the low-pressure liquid refrigerant evaporates to form gas refrigerant, heat is absorbed by the refrigerant. As such, you get cold air blowing out from the aircon. The evaporator is frequently called the aircon fan coil.

This cycle repeats continuously to cool the room. This is a very simple explanation of the refrigerant cycle in an air conditioner or AC system. Refrigerator also uses the same concept as the aircon.

Aircon in Singapore

Without aircon, most of us living in Singapore will find life less enjoyable. Aircon is installed in most of our homes and offices as well as cars and buses. A large part of our electricity is consumed by it. Therefore it is important for us to go green and use more energy efficient aircons. Energy efficiency aircon has NEA label of 4 to 5 ticks. Please buy these energy efficient aircon for installation to save the earth. It will only cost you a little more to be environmentally friendly. Aircon should also be cleaned and serviced regularly to maintain its efficiency. If it is dirty, it tends to use more electricity. Cleaning can be normal cleaning, steam cleaning, chemical wash or overhaul.

Aircon will continue to serve us in the future and will evolve to be even more powerful and energy efficient.

Furthermore, as more households own … ......

Aircon chemical wash

Aircon chemical wash is the process of cleaning the aircon with chemical solution. Sometimes aircon chemical wash is mixed up with aircon overhaul. Let us explain further here.Aircon Chemical Wash versus Aircon OverhaulAircon overhaul is more complicated. It involves dismantling of many parts of the aircon and cleaning it with chemical solution. It is usually not performed at the owner’s premises.Aircon overhaul is usually performed every three to four years so that smaller parts and … ......

Aircon Steam Cleaning

Aircon steam cleaning is less common compared to aircon chemical wash. However, it is gaining popularity. Why is aircon steam cleaning good? Unlike aircon chemical wash, it does not use chemical solution which may corrode aircon components. It sprays steam and hot water on the affected areas. This is an excellent way to clean and disinfect your aircon. It also removes the damp smell from aircon.When an aircon specialist perform aircon steam cleaning, he must ensure that he has a … ......
